# define functions  

def add(x, y):  

   

   return x + y 

def sub(x, y): 

   

   return x - y 

def mul(x, y): 

   

   return x * y 

def div(x, y): 

   

   return x / y  

# take input from the user  

print("Select operation.")  

print("1.Addition")

print("3.Multiplication")  

print("4.Division")  

  

choice = input("Enter choice(1/2/3/4):")  

  

num1 = int(input("Enter first number: "))  

num2 = int(input("Enter second number: "))  

  

if choice == '1':  

   print(num1,"+",num2,"=", add(num1,num2))  

  

elif choice == '2':  

   print(num1,"-",num2,"=", sub(num1,num2))  

  

elif choice == '3':  

   print(num1,"*",num2,"=", mul(num1,num2))  

elif choice == '4':  

   print(num1,"/",num2,"=", div(num1,num2))  

else:  

   print("Invalid input")  

OutPut:

Select operation.

1.Addition

2.Subtraction

3.Multiplication
